As we refine a Class Model, one thing to consider is changing the 'location' of attributes through inheritance. Many of the classes have attributes, and some attribute values are shared among multiple classes. When all subclasses have a particular attribute in common, we might move this attribute to the superclass. Considering our Restaurant example, which of the attributes listed below would be good candidates for raising to a superclass? Select all that apply. Note: there is a negative score for selecting an attribute that should not be raised.
